METHOD AND QPPARA'TUS FOR BEAMING. WARP.

Application filed July 27, 1921. Serial No. 487,883.

To all whom it my camera:

Be it known that 1, JOHN W. SOEN, a citizen of the United States, residing at Roxborough, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Methods and Apparatus for Beaming Warp, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to an improvement in the method of beaming warp and apparatus for carrying out the method. The object of my invention is to provide an efficient method of beaming, whereby a warp having a relatively large number of ends may, be quickly nd properly beamed from tubes of yarn, by relatively cheap labor, as well as t provide automatic apparatus for carrying out the method, so that the human element is substantially eliminated so far as broken or slack ends or warp threads is concerned'.

My improved method has proven very satisfactory for beaming warp for Weaving double pile fabric or plush.

Prior to my invention it has been customary for the beamer to beam chain or bale warp, and during the beaming, separate and examine the warp threads or ends and splice the broken threads; As chain warp is made up of the specified number of ends or threads in strand form, laid up and coiled and shipped in bale form, the threads or ends are broken in various places by handling, so that the beamer must exercise great care when beaming and splicing the broken ends, and particularly when beaming beams for plush looms. As such great care is required for beaming of this character, highly skilled beamers who command a high wage must be employed.

Another object of my invention is to provide a method of beaming whereby the stock of warp may be standardized, so that themill owner can'readily make up warp beams with the required number of ends or threads without the necessity of carrying a large and assorted stock of different numbers of ends.

In carrying out my invention for beaming warp having a multiplicity of warp ends, I use a creel which will hold the required number of tubes of yarn, and wind the-ends directly on the beam from the creel. The ends in their passage from this creel to the beam pass over various tension rollers, about a measuring drum and through an automatic stop device, supplemental to the usual stop device, on the creel. This supplemental stop device is arranged to automatically stop the machine if any of the ends are slack or broken between the guiding eyes for the ends passing from the. creel and the measuring drum; and which will also act to stop the machine if any of the ends should break between the creel and the supplemental stop which has been picked up chain warp with and carried along by other threads before i' the regular stop on the creel fell into its stopping position, so that the danger of broken ends on the beam and two ends passing through in place of one is substantially eliminated.

Fig. 1 of the drawings is a side elevation in diagram of one form of apparatus for carrying out my invention.

ig. 2 is a perspective view, somewhat diagrammatic of a portion of Fig. 1.

In the drawing the reference character 5 designates the creel for supporting the required numbers of tubes 6 of yarn to make up a beam having the required number of ends.

The threads from each spool or tube passes through a stop which is arranged to stop the entire machine if the thread on the tube is broken, The stops are connected electrically in the usual manner with a suit able annurciator to indicate to the operator the location of the broken end, so the broken end can readily be traced and spliced. Each thread passes from its guides and stop on the creel through a guide eye on a' board 7.

The various ends pass from the guide eye board 7 under and over guide rollers 8 and 9, and then through a separating device 10,

consisting of a lurality of wire eyes similar to heddles, 1n which alternate threads pass through the eyes while the others ass between the wires forming the eyes. nehalf of the ends then pass over a separating bar 11, while the other half passes under said bar. The ends then pass from the bar 11 through a reed 12 and a supplemental stop device 13, which are arranged to keep the various ends separated so that the stop- 13, which controls electrical devices, will etc the beamer if any of the ends are slack or roken, as hereinafter described.

14: is a guide roller over which the ends pass from. the stop device 13, and 1a is a measuring drum about which the ends pass from-the guide roller 14. to a guide roller 15. 16 is a second separating bar below the guide roller 15, one-half of the ends passingaroundone side thereof while the other half passes about the other side. 17 vis a second reed between the bar 16 and the warfi beam 18 on which the .ends are wound. is a bearing, there being one on each side of the machine for supporting the warp beam.

l8. 19 is a tension device or press for the warp beam comprising a longitudinal bar, which engages the ends or warp threads as they are wound on the beam, and which bar is carried by two weighted levers which are arranged to hold the bar against the wound warp with an equal pressure throughout the winding of the beam, by means of suspended weights.

The machine is driven by suitable mecha nism hereinafter described to cause the ends to be drawn from the various tubes 6, around and through the various guides and separat ing devices, as well as the electrically controlled stops, by the rotation of the warp beam 18. The various guides are arranged to place the ends under tension and also to maintain the various .endsseparate "from each other as well as to uide the various ends to their proper positions on the warp beam.

it any oi the ends should become slack or broken between the measuring drum and the step 13, the machine will be immediately stopped, after the operator has spliced the end and placed it under the proper tension between the measuring drum and a point back of the stop device, the machine can again be set into motion.

it frequently occurs that an end breaks between the guides en'the creel and some of guides between the creel and the measuring drum, and very'lrequently the end will be piclred up by one cf the other ends and drawn ahead, thereby before the stop on the creel has time to fall into stopping position, and as the broken end continues to be drawn from insane-a By placing a supplemental stop device adjacent to the measuring drum or near the 'point of greatest tension of the ends,.l[ am manner, which is in turn driven from-.-

a pulley )Jl'by a belt 22. 23 is a driving pulley onthe shaft of the pulley 21 driven by a belt 24ltrom any suitable source. The pulley23 is arranged to be connected to the pulley 21 by means of a clutch 25 which is arranged to be thrown by hand to connect the pulleys to each other and is retained in driving relation by an electrically actuated latch 26. This latch is arranged to release the clutch to stop the. machine when the latch magnet 27 is-energized.

28 is a battery or source of electrical energy one pple of which is connectedto a contact 29 on the stop l3. 30 are contacts one on each side of contact 29 which are interconnected and are connected to one pole of magnet 27. lhe other pole of the magnet is connected to the other pole of the battery. The stop 13 is provided with a plurality of circuit closing lingers 31 of the usual type, there being one "for each warp thread or end, and are arranged to separate the threads, while the tension on the ends will hold the lingers out of engagement with contacts 29 and 80. If one of the threads should become slack or broken, its circuit closing finger will drop and close the circult through the magnet E27, release the clutch 25 and stop the machine. The stops on the creel each comprises a pivoted finger 32 having an eye through which the thread passes from the tube or bobbin 6 to its eye in the board 7. The finger 32 is connected to one pole of the battery 28 and 33' is contact connected to one pole ct magnet 2i", the arrangement being such that when any of the threads brealr near the tube, its linger will drop, close the circuit through magnet 27, and stop machine.

The advantages of my invention result from the provision of a method of beaming warp in which the various strands "for the warp are Wound direct from individual proper number ends, as required so that the milPs entire stmlroi yarn merely consists of individ "-t-l tubes of yarn er ends instead of large stoclr baled warp of ditrferent numbers e -r'ts.

lllll lll) the individual threads from each incense the bale.

This methqd not only permits the employment of relatively cheaper labor as compared to warp beamers, but by my method the time consumed in beaming is materially reduced, which not only reduces cost of production, but also reduces the floor space required for beaming.
